VIC and video timings
A VIC is a code number for an exact video format, such as VIC 97 for 3840×2160 at 60 Hz, used in EDID and InfoFrames.
A VIC is a short number that stands for one exact video format. VIC 16 means Full HD at 60 pictures per second; VIC 97 means UHD at 60.
It works like a menu number in a restaurant: instead of describing the whole dish, the source and the TV just say "number 97" and both know exactly what is meant.
Does the HDfury Vertex show the VIC of my signal?
YESYes. The OLED RX INFO page shows the VIC of the incoming signal, e.g. 'VIC 97 3840x2160p60 12-bit'. The Vertex accepts TV timings from 480i to 2160p60 and PC (VESA) modes within 600 MHz.
How to use it with the Vertex:
- Short-press INFO/OLED until the RX Info page appears (p.9, p.19).
- Read the VIC line, e.g. VIC 97 = 3840x2160 at 60 Hz (p.19).
- In the GUI AVI/VSI IF tab you can see the captured AVI InfoFrame, which carries the VIC (p.34).
- Only replace the AVI InfoFrame if you know what you do: wrong values can blank the screen (p.34).
What it is
VIC stands for Video Identification Code. The codes come from the CTA-861 standard used by HDMI. Each code fixes a complete video timing: the visible pixels, the refresh rate, the aspect ratio and the hidden blanking time around the picture that together set the pixel clock.
The display lists the VICs it supports in its EDID. The source picks one and announces it in the AVI InfoFrame that travels with the video, so the display knows what is coming. Some sources identify 4K24, 4K25 and 4K30 through a separate HDMI VIC in the vendor-specific InfoFrame instead.
Computers often use VESA timings instead of CTA VICs. That is one reason why a TV can accept 3840×2160 from a Blu-ray player but refuse the same resolution from a PC: the exact timing is different.
On the Vertex
The OLED RX INFO page shows the VIC of the incoming signal, for example "VIC 97 3840x2160p60 12-bit" (p.19). In the USB GUI, the AVI/VSI IF tab shows the captured AVI InfoFrame, where the VIC is stored; advanced users can replace that InfoFrame, but wrong values can blank the screen (p.34).
The Vertex accepts SD, HD, Full HD and UHD TV timings from 480i up to 2160p60, and PC (VESA) modes, as long as the signal stays within 600 MHz (p.103–104, p.111).
Common questions
What does VIC 97 on my Vertex OLED mean?
It is the standard code for 3840×2160 at 60 Hz. The line on the RX INFO page tells you the source is sending UHD at 60 Hz (p.19).
Why does my TV reject a PC resolution that looks the same as 4K?
The PC may use a VESA timing with different blanking than the CTA timing the TV expects. Choosing a TV timing (3840×2160 at 60 Hz, not a custom mode) usually fixes it.
Does the Vertex support PC resolutions?
Yes. The manual says all PC graphics modes within 600 MHz are supported, including 4K (p.103).
